Te hiki me te whiu, te hiki, te here
I te mea he kaihanga mekameka hono maitai a tawhio noa mo te 30 tau, kei te noho tonu to maatau wheketere me te mahi i te waa tino nui o te hangahanga mekameka Hainamana te whanaketanga o te ahumahi e whangai ana mo te maina (ko te maina waro, ina koa), te hiki taumaha, me nga whakaritenga kawe ahumahi mo te hurihanga kaha teitei. mekameka hono maitai.Kare matou e mutu ko te kaihanga mekameka hono a tawhio noa i Haina (he nui atu i te 10,000T te utu o ia tau), engari kia mau tonu ki te hanga me te mahi auaha.
